REINFORCING FRAME Russian patent published in 2002 - IPC

Abstract RU 2190068 C2

FIELD: construction, applicable in manufacture of bearing building members. SUBSTANCE: the reinforcing frame, mainly for a cellular-concrete flexible product, for example, a slab has the shape of a bar lattice truss made either of separate bars, or of a single zigzag bent bar. The optimum value of the diameter of the lattice bars corresponds to expression , and the calculated value is rounded off towards the increase to the nearest integer. The value of the acute angle between the lattice brace and the truss chord corresponds to expression , also with rounding-off towards the increase to an integer of degrees, where d - diameter of bars of the transverse reinforcement of the frame (truss lattice), mm; q - design linear bending load perceived by one frame, kgf/cm; L - design frame span, cm; Rp-design strength of bar of the frame transverse reinforcement (truss lattice member), kgf/sq.cm; α - acute angle between the brace and the truss chord, deg. EFFECT: reduced consumption of metal in manufacture of a reliable reinforcing frame. 5 cl, 4 dwg, 4 ex
